I sometimes intentionally short-stroke my 1300 to eject a round without chambering another when I wish to unload the gun.
After shooting lighter 2.75" shells for the summer, the recoil of heavier 3" hunting loads can make the gun and slide action "feel" different, resulting in a potential missed feed. This can be overcome by deliberately racking the slide back hard.
The 1300 is a fine gun. Keep the rails and receiver innards clean and lubed, and practice often enough to keep basic form automatic.
